Answer:
Q1. The perimeter of the lid of the box can be calculated by adding the lengths of all four sides. Therefore,
Perimeter = 9 + 9 + 18 + 18
Perimeter = 54 inches
Q2. To calculate the amount of jello required to fill the box, we need to find the volume of the box. The volume of a rectangular prism can be calculated by multiplying its length, width, and height. Therefore,
Volume = 9 x 18 x 17
Volume = 2754 cubic inches
Thus, 2754 cubic inches of jello will fill the box.
